Hello again, I noted today that geometries that have been removed using this method continue to be drawn in the display. I have an Agent class that inherits from MasonGeometry; this particular agent can "die" during simulation and its stop() method is invoked. When this happens with an agent stored in a Continuous2D, for instance, invoking the remove() method is enough to prevent it from being drawn again. After invoking removeGeometry() is there anything else referencing the geometry? Thank you, Luís On 21 March 2013 18:58, Mark Coletti <[log in to unmask]> wrote: > > I've added removeGeometry() and committed the changes to subversion.
